First, please note that drawings are almost always drawn in real size (1:1) with a CAD system. If this is not the case, please correct your drawing first.

If your drawing has a drawing border or header, scale the border or header instead of scaling your drawing. For example, if your drawing is to be printed with a scale of 1:5 (factor 0.2 or five times smaller than real size), scale your drawing border or drawing header with a factor of 5, i.e. insert it five times larger than you want it to print.
